Flexible sort, odd making stand (7)
I believe the answer is:
rostrum
'stand' is the definition.
(thesaurus)
'flexible sort odd' is the wordplay.
'flexible' indicates anagramming the letters (I've seen this in other clues).
'odd' becomes 'rum' (I've seen this before).
'sort' is an anagram of 'rost'.
'rost'+'rum'='ROSTRUM'
'making' acts as a link.
(Other definitions for rostrum that I've seen before include "At which one may conduct" , "Platform for orchestra conductor" , "Platform for speaker" , "Conductor's dais" , "Platform for public speaking" .)
